Start to Suppress the Gods and Demons

The will of heaven changes, the human race declines, and the demon race rises. The human race, which once came to the imperial court from thousands of races, retreated to "Little Kyushu" after experiencing the "War of Ten Thousand Races in Kyushu". Under various crises, the human emperor married his daughter, and the human race sent geniuses to refine medicine for the demon gods... Only in exchange for the human race to cultivate and live. Since then, the demon clan has established itself as the overlord of the "Great Nine Provinces", and the human race has been reduced to food, medicine, and slaves... How can the young man here not be so brilliant? "It is our duty to rebuild the supreme glory of the human race!" How can the young man here be willing to have gods, demons, and ghosts messing around in Kyushu? "I'll be the one to suppress the gods and demons!" [Introduction a bit outdated?
